This invention relates to new and useful improvements in hoists intendedto handle cardboard, paper, metal and any other material used inprinting, box making, lithographing and allied arts.

The principal object of the present invention is to provide a hoistwhereby all materials formerly handled by hand are now movedautomatically without any manual eifort, thereby immensely acceleratingproduction.

Another important object of the invention is to provide a hoist of thecharacter stated whereby loads can be trucked into the hoistingapparatus thereby eliminating the necessity of repiling materials.

Other important objects and advantages of the invention will becomeapparent to the reader of the following specification.

In the drawings:

Figure 1 represents a front elevational view of the apparatus.

Figure 2 is a side elevational View.

Figure 3 is a cross sectional view showing one of the rail attachingmembers.

Figure 4 is a fragmentary top plan View.

Figure 5 is a cross sectional view taken substantially on the line 5-5of Figure 6.

Figure 6 is a sectional view taken substantially on the line 5-5 ofFigure 5.

Figure '7 is a sectional view taken substantially on the line 'I"! ofFigure 5.

Referring to the drawings wherein like numerals designate like parts, itcan be seen that the apparatus includes a pair of inclined eye beams 5which extend upwardly from floor plates 6 to a machine table I. A bar 8connects the lower portions of the beams 5, 5 and rising from this bar 8are spaced guide slats 9 extending upwardly and backwardly over themachine part I.

The carriage part of the hoist consists of a pair of I beams I0, II]which have spring strip bumpers II on the bottom thereof to withstandshock when the same are lowered onto the floor. These beams II) areconnected by chains I2. Observing Figure 2, it can be seen that a truckI3 can be moved into position with edge portions of its platformoverlapping the rails or beams III.

The upper flanges of these beams I are formed with recesses I4. A doublehook member I is provided for each end of each of the bars I0 andembraces the upper flange thereof, and each of these double hook membersI5 has a swingable latch member I6 engageable into the correspondingnotch I4 to prevent accidental shifting of the double hook member on thecorresponding bar ID. A connector I1 is provided between each hookmember I5 and a corresponding lift chain Forwardly inclined I beams I9extend from the intermediate portion of each of the beams 5 and thesebeams I9 have upstanding members 20 on which are bearings 2|,complementary to bearings 22 on the upper ends of the beams 5. Thesebearings 2| and 22 accommodate the forward and rearward ends of shafts23 and 24. On each of these shafts 23 and 24 is a pair of chain pulleys25 over which the corresponding chain I8 is trained and the free end ofeach of these chains I8 is provided with a handle 26. The pulleys 25 aresuitably keyed through hubs 21, as shown in Figure 5 denoted by thenumeral 28 tothe shafts 23 and 24. Each of the pulleys 25 has a guardhousing 29 circumscribing the same and provided with guide tubes 30 and3I depending therefrom for guiding the two flights of the chain, theseguides 30 and 3| being of cross shape in cross section, definingcross-shaped passageways for the links of the chains I8. The guides 30and SI have tail portions 32 which are attached to cross bars 33bridging the upper ends of the beams 5 with the members 20.

Mounted on the upper portion of one of the inclined beams I9 is anelectric motor 34 having an armature shaft on which is a pinion 35.Mounted upon the upper portions of the members I2 are plates 36 havingbearing formations 31 through which a shaft 38 is trained. The endportions of this shaft 38 have worms 39, 40 which mesh with overlyinggears 4|, 42 on the shafts 23 and 24, respectively.

One end of the shaft 38 has a sprocket wheel 43 and a sprocket chain 44is trained over this sprocket wheel and the pinion 35.

Obviously, a truck I3 can be driven over the beams I0 while they arelying flat on the floor, after which the hooks I5 can be engaged withthe beams I0, this being done by the trucker, after which the motors 34can be controlled by the pressman from a remote point.

While the foregoing specification sets forth the invention in specificterms, it is to be understood that numerous changes in the shape, sizeand materials may be resorted to without departing from the spirit andscope of the invention as claimed hereinafter.

Having described the claimed as new is:

A hoist of the character described comprising substantially uprightbeams, a pair of shafts at the upper ends of the beams, drive means forthe shafts, pulleys on the shafts, lines trained invention, what is overthe pulleys and structure engageable beams to which the lower ends ofthe lines are attachable, and detachable means for attaching the lowerends of the lines to the beams, said beams being of I-shape in crosssection, said detachable means consisting of a double hook for each ofthe lines for embracing the upper flanges of the corresponding beam,said beams having notches therein, said double hook members havingdetents thereon for engagement in the notches.
